I put a 10,000-species bird sound model into my React Native app. Wrote up how.

The license trap, 409 MB to 105 MB, and why raw scores aren't probabilities. https://t.co/QeBMdKwiRj

@DevWith_Atul Hi, sure let's connect!

Shipping an ML model in a paid app? Check the license of the weights, not just the repo.

The best-known bird sound model, from Cornell: code MIT, weights CC BY-NC-SA. No commercial use.

I went with an open model from Google instead. Apache 2.0, ~10,000 bird species.

[Mike Ciechanowicz @MikeCiech]

Well, that was fast… crossed 200 already! 🤯 Appreciate everyone who connected today. Back to coding!

[Mike Ciechanowicz @MikeCiech]

@sayoojkeloth Thanks bro! Honestly, active engagement — replying meaningfully to other builders.

@1k_clouds Hi, connected!

[Mike Ciechanowicz @MikeCiech]

@098uyiubgvgcss Good catch, that would bite with raw logits. I softmax over the bird classes first, then multiply those probabilities by the country weight, so it's all positive. Skipped that step in the article.
